NEW Celtic loan signing Odsonne Edouard and £166million wonderkid Kylian Mbappe were friends growing up in the suburbs of Paris.

Now the strike duo are preparing to cross swords in the glamour of the Champions League.

Both were involved in deadline-day moves, Edouard sealing his switch from Paris Saint-Germain and Mbappe becoming the world’s most expensive teenager as he joined PSG from Monaco.

Mbappe’s move is on an initial season-long loan, but the big-spending French outfit have an obligation to buy him for £166m next summer. PSG structured the deal this way in a bid to get around financial fair play regulations, but that hasn’t stopped UEFA opening a formal investigation.

Edouard, 19, is thrilled to see French Under-19 team-mate Mbappe, 18, make the move back to their home city.

And he is already looking forward to PSG’s visit to Celtic Park for the Group B opener on September 12.

Edouard said: “I know Kylian very well because we are childhood friends.
